Given numbers are 128,675,473,872

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 128,675,473,872 is 4454524800.

Find LCM of 128,675,473,872 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 2 x 16 x 675 x 473 x 109 = 4454524800

Therefore, the lowest common multiple of 128,675,473,872 is 4454524800.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

128 x 675 x 473 x 872 = 35636198400

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

128 : 1, 2, 4, 8, 16, 32, 64, 128

675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675

473 : 1, 11, 43, 473

872 : 1, 2, 4, 8, 109, 218, 436, 872

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,675,473,872, is 1.

Now, the common factors can be found like this.

128:2x 2x 2x 2x 2x 2x 2

675:3x 3x 3x 5x 5

473:11x 43

872:2x 2x 2x 109

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2 = 8

Therefore, the value for common factors is 8.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 35636198400/(1x8)

LCM = 35636198400/8

LCM = 4454524800

Thus, we can understand that the LCM of 128,675,473,872 is 4454524800.
